The Tier One system: a focused path to IELTS 7.0.

01

Live Group Classes Every Week

Small group, head instructor, real coaching, focused on the writing and speaking you submitted that week. One live class a week in Tier Zero, three a week in Tier One. Miss one? Every class is recorded and posted to your dashboard.

  • 1 live class/week in Tier Zero, 3/week in Tier One
  • Topics built around what your group submitted
  • Recorded and usually posted within 24 hours.
02

Daily Assignments In One Dashboard

Every morning the dashboard hands you the day's assignments: a reading passage, a listening section, a writing task, a speaking prompt, and the vocab due for review. Each one timed the way the real exam runs. Reading and listening score the moment you submit; your writing and speaking are graded by AI, with your instructor reviewing your assignment writing.

  • A built lineup of assignments waiting every morning
  • Each one timed exactly like the real IELTS exam
  • AI-graded, with instructor review of assignment writing
03

A Dedicated Self-Study Manager

Even the best curriculum can't stop burnout when you study alone. A 1:1 learning manager is assigned to you to keep you motivated, hold you accountable, and build your study plan together, so you actually finish the program.

  • Weekly 1:1 check-in to keep you on pace
  • Replies usually within the business day.
  • Keeps you motivated so you don't fall behind
04

A Weekly Progress Report

Every week, a personalized report breaks down the band you'd score today, the trajectory you're on, and the sub-skills holding it back. Per-skill, per-question-type. No guessing, no false confidence.

  • Per-skill band breakdown, refreshed every week
  • Trajectory chart shows whether you're on track
  • The three sub-skills to fix next, ranked

From the Founder

I built this because I wished it existed for me.

I spent two years trying to push past IELTS 6.5 in big classrooms in Seoul. The feedback I got back was always some version of "study more." My band score didn't move, and I didn't know what to fix.

So I became a teacher. Eight years at a Gangnam (P) academy teaching IELTS Writing and Reading. And I saw the same gap from the other side: lessons get optimized for the middle of the room, and students who should be hitting 7.5 plateau at 6.5 because no one tells them, specifically, what to fix. The work isn't personal, so the scores aren't either.

Tier One is the program I wish I'd had. I built a system that tells each student, one-on-one, exactly where they're falling short and helps them fix it right then. IELTS burns people out, and when life gets busy, completion rates drop. So a dedicated learning manager personally supports your studying one-on-one.
